Fedora Security :: Off-the-Record Plugin - SHA-1 Or SHA-2?
Jun 20, 2010
Ive being digging around the net for some clarification about the Off-The-Record plugin for Pigdin (and other IM's). Basically i want to know if it uses the SHA-1 or SHA-2 hash function. Some might say im wearing my tin foil hat but the SHA-1 was cracked in 2005 and as far as i know SHA 2 is much more secure.
Wikipedia states it's SHA 1 and the authors of the OTR plugin mention both SHA-1 and SHA-2 in their documentation, and i couldnt find an active pidgin forum (could only find the archived pigdin forums on sourgeforge)

I've got Pidgin 2.4.1 on my Hardy computer, and I got the 'Off The Record' plugin working with no problems: I went to Tools > Plugins, found 'Off The Record' in the list of plugins and checked the box - and now OTR works.On my Jaunty machine I've got Pidgin 2.5.5 installed - and I can't find the OTR plugin! I go to Tools > Plugins and look through the list, but OTR isn't there!

When I am installing texlive package power gone suddenly. From that time onwards yum update command is not working. It is giving error as follows:

You could try using --skip-broken to work around the problem

yum-complete-transaction first
rpm -e texlive
yum install libkpathsea.so.4

In our organization we use Static IP addressing scheme(Some departments have DHCP which is not related to this thread). We use Squid as proxy.
We assign each machine its IP address and make entry in our TinyDNS database, and provide those details to users, which they manually enter in their config and then access the network. We assign different range of IPs to different departments. This we consider as the "proper way" for our organization.
But we have found that lot many users are simply guessing some IPs and using them without having any entry in our DNS record. Though this works for some, most of the time we end up having IP conflicts and disorganization in our organizational allocation policy.
So, my question is, How do I block the specific IPs whose entry is not explicitly defined in our DNS record. In other word if the IP 192.168.20.15(lets say he is jack.ourorganization.com) is defined in our DNS, we should allow access... where as if IP 192.168.20.16(this does not translate to any user as it is not defined in our DNS) is not defined in our DNS we should not allow it access to our network.

I have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet been able to remove the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU.
Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus? Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.

I'm posting an E-Mail I sent to Pidgin Support, which didn't get answered. I'm doing this because I believe it is a general SSL problem. I've even tried a different chat client (Instantbird) - same error message. Since a week or so I'm not able to securely login to ICQ any longer with one of my accounts. Only if I disable "Use SLL" in the advanced settings, it works. With SSL I get the error message "Unable to connect to BOS server: SSL Handshake Failed". In the debug window the reason for the failure is "A record packet with illegal version was received". If I enable the setting "Use clientLogin", I get a different error: "Received invalid data on connection with server".
I get this error for all of my ICQ accounts if I enable this, but the other ones work just fine using only "Use SLL". I can login to the ICQ website with the "bad" account too, the settings are exactly the same for all 3 accounts. I was using Pidgin 2.7.3 when this happened first, upgraded to 2.7.5, but no change. I'm running RHEL 5.5 x86_64. I've attached the Pidgin debug messages for the "bad" case of the not working account and for the "good" case of one of the working accounts. I've tried a lot of things, like deleting the account and adding it again. I deleted the cached certificates. I changed the password on the ICQ website.
From the attachment I'm only pasting the most important part - the error message:
(20:27:14) gnutls: Starting handshake with bos.oscar.aol.com
(20:27:14) gnutls: Handshake failed. Error A record packet with illegal version was received.
(20:27:14) oscar: unable to connect to FLAP server of type 0x0002
(20:27:14) connection: Connection error on 0x9bf19f0 (reason: 0 description: Unable to connect to BOS server: SSL Handshake Failed)
I doesn't get into my head why 2 accounts work perfectly, but one doesn't. The login-server is exactly the same, so also the used certificate should be the same.

A computer security researcher has released a plugin for Firefox that provides a wealth of data on Web sites that may have been compromised with malicious code.
The plugin, called Fireshark, was released on Wednesday at the Black Hat conference. The open-source free tool is designed to address the shortcomings in other programs used to analyze malicious Web sites, said Stephan Chenette, a principal security researcher at Websense, which lets Chenette develop Fireshark in the course of his job.

Quote: It's no secret that Web sessions that use the bare HTTP protocol to transmit and receive data are susceptible to a variety of security attacks. What's less clear is how much information is floating out there in the ether, especially with the rise of "Web 2.0" and rich social networking applications and other Web based sharing tools.
But now a pair of researchers have created a tool to identify and capture the social networking sessions of those around you. The tool, a Firefox browser extension dubbed "Firesheep," was demonstrated at the ToorCon Hacking Conference in San Diego on Sunday. Its primary purpose is to underscore the lack of effective transaction security for many popular social networking applications, including Facebook, Twitter, Flickr and iGoogle: allowing users to browse public wifi networks for active social networking sessions using those services, then take them over using a built-in "one-click" session hijacking feature. Firesheep works on unencrypted wireless LAN connections with services that do not use secure HTTP.

While using Rhythmbox this morning, I was greeted by a blunt and undiscriptive error message:
Code:
Plugin Error:Unable to activate plugin Cover Art.Going to the plugin page, I was supprised to find that most of the installed plugins would not load. Without any info being offered in the player, I looked on line. Many people had problems with other plugins, and most of the time it was a problem with an uninstalled python package. But I checked on this site and I found that I had all of these packages installed. (Well, the python ones at least, to check all of them would take forever.)

After finding no help there, I ran rhythmbox -d to debug:

I'm running Fedora 15 XFCE spin, Audacity 1.3.13-beta and my sound is ALSA/Pulseaudio (I'm not totally sure what these are anyway, are they drivers?) Anyway, when I'm in Audacity and I go to the record options I can choose from default, pulse, and HDA ATI SB:ALC268 Analog (hw:0,0). If I try any of these three options and press record I get static. Here's a screenshot of what it looks like to press record for each of the three options in order.
[URL]
The last option won't even record nothing, it just doesn't work. Also, if you look where the little picture of the microphone is, the option to drag the input volume is greyed out.

I recently installed Fedora 15 on a new laptop (after, of course, deleting the pre-installed virus that came with the laptop). I installed the normal suite of tools using yum, including gcc. However, I cannot even build and run Hello World, so now I really feel like I don't know what's going on.
Code: #include <iostream>
int main (int argc, const char *argv []) {
std::cout << "Hello, world ";
} Build: Code: g++ -o main.o main.cc -g -Wall -pedantic
g++ -o hello main.o -g -Wall -pedantic -nostartfiles
/usr/bin/ld: warning: Cannot create .note.gnu.build-id section, --build-id ignored.
/usr/bin/ld: warning: Cannot create .eh_frame_hdr section, --eh-frame-hdr ignored.
/usr/bin/ld: error in main.o(.eh_frame); no .eh_frame_hdr table will be created.
That doesn't look too promising, but they are warnings, and an executable was created, so try running it:
Code: ./hello
./hello: error while loading shared libraries: ./hello: unsupported version 30277 of Verneed record. I have not had any success understanding what is wrong from googling, so I am now trying it here.
Let's see:
Code:

i installed ubuntu inside windows but someone instead of uninstalling it directly deleted the ubuntu folder inside windows ,thinking that the partition will be deleted. but when i restarted the system and command prompt came and said unable to find boot record and i couldn't boot windows as well and a grub prompt came like grub>, then i inserted the windows boot cd and repair the boot record error but my problem is , instead of doing this way, can i do so by grub prompt directly without using winidows cd.

I try to boot Fedora 10 without initrd. System boots normally if I make in some nodes in /dev such as /dev/console. Almost everything works fine, but when I try ping with record route option -R I get this error
Quote:
ping: record route: No message of desired type
If I boot with initrd ping -R works without this error. Iptables not running.
Also this error appear when I try to boot from LiveCD F11-Alpha-i686-Live-KDE.iso or other Fedora 10 LiveCDs.

I want to set up a web server on a PIII machine with about 800MHz processor and just under 500 megs of RAM. So how would I go about configuring Fedora 12 to do this? I've tried the small spins and I just don't know how to configure it so it will install properly. I was able to get the Gnome spin on it but when it booted I couldn't get through the log-on screen. I have an AGP NVIDIA Geoforce 6200 video card. I'm wondering it that's it. The only Linux distros I could get on the machine was Puppy and Debian. Puppy did not edit the boot record very well. Debian went on there with very minor issues, but edited the master boot record very well so that I can dual boot to WindowsXp HE. I also tried to put Centos on there but the Live CD is not installable. I have to make an installation CD from the DVD Package. Anyways, as far as Fedora is concerned, I just want a utility, light weight spin that has web-server, mail server, and eventually MySQL. Other wise I'll have to commit treason and use the horned Debian as my savior in this battle.
